The European Broadcasting Union has published a new protocol, developed in close collaboration with ATEME and Nevion, that enables real-time entitlement management for content streams over any network.

The EBU describes BISS-CA as an “on/off switch on the sender’s side”, controlling whether a specific receiver can decode a given signal.

The cryptographic entitlements are transported together with the live video content, allowing the rights holder to grant and revoke usage rights in real-time. BISS-CA also includes safety measures such as watermarking, which makes live content traceable and discourages piracy.

Dr Hans Hoffmann, senior manager at EBU Technology and Innovation, said: “This is a much needed technology that fills a long-standing gap. With BISS-CA, business partners can now exchange live content, regardless of which vendor systems they operate.”
